In the latest addition to the series of pet battle dungeons, we are revisiting the old home town of the Gnomes: Gnomeregan!

To start your journey through this dungeon, head over to Radek Fuselock in Dazar’alors “Hall of Beasts” if you're Horde or Tizzy Gearjolt at Boralus’ “Ruff Waters” for Alliance players. The breadcrumb leads you directly to the instance entrance of Gnomeregan, where you will meet Micro Zoox who will offer you the instance quests, start the queue for it and also sell you pets related to the Gnomeregan dungeon!

If the strats on this page can be used for the Challenge Mode too, why didn't you make a list of all pets used so we can put pets other than those in the fights with 'extra slots' ? I miss that, unless those strat aren't final, but it would save a lot of page viewing just to pinpoint those pets.

Some substitutes:
Tiny Shale Spider can replace a Shale Hatchling, or use a double of any other Shale Hatchling.
Silkbead Snail and Rusty Snail can replace any of the other snails, or use any snail you have double.
Emmigosa can be used instead of Azure Whelpling.
Golden/Silver Dragonhawk Hatchling can replace Red / Blue Dragonhawk Hatchling.
Withers can replace a Teldrassil Sproutling or Ruby Sapling.
Tainted Cockroach can be replaced with ~20 other cockroaches/beetles.

The "default" is different for each person, I believe, if they have imported their pets. It chooses what strat you have pets for or are closest. I've seen my suggested strats change as my pet collection grows.

Exactly what JestersTear wrote. That's why the "top" strategy doesn't exist anymore, it's different for every user. The tables I had previously don't work anymore with that new system and need a re-make.

Saw a post on wowhead that said you could logout and onto an alt and then use bandages to heal pets between fights, then log back in on the dungeon runner, apparently you stay in the dungeon doing this, haven't tested it myself yet.

I'm not sure about logging out and in. I had to log out in the middle of the dungeon and when I came back I was at the beginning and needed to do all the fights again. This was in the regular mode dungeon.

Found a great tip on Wowhead forums for getting to entrance if you are Horde:

"If you're horde, the ideal, death-free way of getting to Micro Zoox is the following:
- go to Grom'gol Base Camp in Nothern Stranglethorn
- take the teleport into Gnomegeran
- create a costum group and instantly leave it (or join an existing group)
- wait a minute to get teleported out of the dungeon
You'll spawn right before the NPC! No deaths, no repair costs!"

Of course! That's something some people trying to focus on for their challenge mode teams & strategies - pets that survive multiple NPC fights to keep the number of different pets small for players without hundreds of unique pets and duplicates at max level. I think Teroclaw Hatchling was one of those MVP pets for Wailing Caverns before Blizzard changed ability slots.
